Mystery 1911 Barrel Proof Marks

[larryh1108]

I found a 1911 .45ACP barrel with some proof marks I cannot identify.
I know that this forum has a plethora or knowledge.
Any idea?
Thanks.

The A into Arrow is a Ballester-Molina Proof.

There is a D that overlays it but your appears to be only half stamped

Thanks!
That symbol on the right looked familiar.
Ballester-Molina makes sense.
This is a great forum!
